Abstract

Onco-microRNAs (onco-miRNAs) are essential players in the post-transcriptional regulation of gene expression and exert a crucial role in tumorigenesis. Novel information about the epitranscriptomic modifications, involved in onco-miRNAs biogenesis, and in the modulation of their interplay with regulatory factors responsible for their processing and sorting are emerging. In this review, we highlight the contribution of bases modifications, sequence motifs, and secondary structures on miRNAs processing and sorting. We focus on several modes of action of RNA binding proteins (RBPs) on these processes. Moreover, we describe the new emerging scenario that shows an unexpected though essential role of selected DNA repair proteins in actively participating in these events, highlighting the original intervention represented by the non-canonical functions of Apurinic/apyrimidinic endodeoxyribonuclease 1 (APE1), a central player in Base Excision Repair (BER) pathway of DNA lesions. Taking advantage of this new knowledge will help in prospecting new cancer diagnostic and therapeutic strategies.

碱基修饰和 DNA 修复蛋白在 onco-miRNA 处理中的新作用：癌症生物学的新见解。

肿瘤微RNA（onco-miRNA）是转录后基因表达调控的重要角色，在肿瘤发生中发挥着关键作用。关于onco-miRNAs生物发生过程中涉及的表转录组修饰，以及它们与负责其处理和分类的调控因子之间相互作用的调控，新的信息不断涌现。在这篇综述中，我们重点介绍了碱基修饰、序列基序和二级结构对 miRNAs 处理和分选的贡献。我们重点讨论了 RNA 结合蛋白（RBPs）在这些过程中的几种作用模式。此外，我们还描述了新出现的情况，即某些 DNA 修复蛋白在积极参与这些事件中发挥了意想不到的重要作用，突出了 Apurinic/apyrimidinic endodeoxyribonuclease 1（APE1）的非经典功能所代表的原始干预，APE1 是 DNA 病变碱基切除修复（BER）途径的核心参与者。利用这些新知识将有助于探索新的癌症诊断和治疗策略。
